Characteristics of the pie chart analysis types

About this task

In Step 2: Choosing a subsystem and specifying an analysis type, you were asked to select one of six analysis types. For the first four types, which are Weekly view by day, Daily view by hour, View of a period of time, and Bar chart, the previous description outlined your choice of specifying n-to-m relations between counters and objects, restricted only by its usefulness.

For the remaining analysis types Pie chart: display 1 counter and n objects and Pie chart: display n counters and 1 object this degree of freedom is not useful. Therefore, when you choose one of these analysis types, the third page of the long-term analysis wizard (the upper part) looks as follows:

For the analysis type Pie chart: display 1 counter and n objects:

Figure 1. Characteristics of long-term analysis type: Pie chart: display 1 counter and n objects

In the left pane, Counters to display shows a tree view of selectable counters. Radio buttons indicate that you can select only one item. In the right pane, Objects to display shows a tree view of selectable objects. The check boxes indicate that you can select multiple objects. This restricts your selections to a 1-to-n relation (which includes 1-to-1) between counters and objects for this analysis type. Note that you can expand the tree items on both sides to select a counter, respectively one or more objects.
For the analysis type Pie chart: display n counters and 1 object:

Figure 2. Characteristics of long-term analysis type: Pie chart: display n counters and 1 object

In the left pane, Counters to display shows a tree view of selectable counters. The check boxes indicate that you can select one or more counters. In the right pane, Objects to display shows a tree view of selectable objects. Radio buttons indicate that you can select only one object. This restricts your selections to an n-to-1 relation (which includes 1-to-1) between counters and objects. Note that you can expand the tree items on both sides to select one or more counters, respectively one object.

When you compare the list of selectable counters Figure 1 and Figure 2, you will notice on the left side that ratios are shown differently in context with counters. In Figure 1 ratios are treated identical with counters because you can select only one counter or ratio (1-to-n relation to objects). Opposed to this, in Figure 2 ratios are shown apart from counters to express their differences (ratios versus absolute values) and to emphasize that you can select multiple counters or multiple ratios (n-to-1 relation to objects). Counters and ratios are mutually exclusive for this analysis type.
